I can buy that maybe Checking from Behind isn’t a perfect fit, per the rule:

When a player intentionally turns his body to create contact with his back, no penalty shall be assessed.

However, the onus is on Wilson to deliver a legal body check, and he’s charging far too fast, especially given the proximity to the boards, to adjust to any changes in direction or facing by Schenn.

Wilson faces a phone interview with the DPS, so he won’t be suspended for more than 5 games. And that’s just a shame; this is exactly the kind of play that the NHL should be removing from the game entirely.
